Stomach bloat doesnt really have much do with sodium ... generally , given that your healthy , its more to do with bad digestion. Ive noticed in my self i cant eat the typical "bro foods" like brown rice , sweet potatoes, and even beef if i go overboard. I end up look looking like im pregnant by my third meal of the day. But my stomach handles faster carbs alot better , chicken , and leaner cuts of beef .
Switch up your foods , and pay attention to how your body reacts to them . Other than that break up your meals in smaller more frequent meals throughout the day . Get enough fiber and veggies in but dont over do it or that will just end up backing you up too. Sip your water throughout the day dont just chug water when you get thirsty .
I dunno thats just off the top of my head , but point is if your having issues with bloating there's alot of other things to look at before you concern yourself with sodium.
